Olympus Corp.'s independent panel investigating the camera maker's acquisitions and accounting may release findings as early as this week, a source involved in the investigation said Wednesday.

The committee plans to complete its report before Olympus announces earnings, the source said, asking not to be identified because the probe is confidential. The investigation is ongoing, so the report could be delayed, the source said.

The Tokyo Stock Exchange has said that Olympus must submit its second-quarter results by Dec. 14 or it will be delisted. Olympus has said it plans to correct previous earnings statements after admitting on Nov. 8 that it had falsified its accounts to hide investment losses dating back decades.
